Why this prototype matters: the game core is pure integer math on a fixed
60Hz timestep. Your keystrokes are recorded per tick, and your score is a pure
function of (seed, inputs). After a game ends, press V and the page
re-simulates your entire run from the input log and checks it reaches the same
score and state hash — the exact check the QUARTERS verifier runs server-side
before any payout. Press R to watch your run replayed from inputs alone,
or C to copy the replay JSON. Saucers shoot back. Extra ship every 10,000.
